Five moles of nitrogen gas is expanded in a piston-cylinder assembly from an initial state of 3 bar and 88 ºC to a final pressure of 1 bar. You can assume nitrogen to behave as an ideal gas with a constant heat capacity CP =7R/2. a) If the expansion is carried out isothermally and reversibly, calculate Q, W, ΔH and ΔU. Draw the process on a pV diagram. Label the axis and the path clearly. b) If the expansion is...

Suppose that we allow 3.50 mol of an ideal gas with Cv=5R/2 to expand isothermally and reversibly from 100 atm, 10 L to 10.0 atm and then the gas is allowed to expand adiabatically and reversibly to a final pressure of 1.00 atm. Calculate q, w, ΔU and ΔH for each step and the total values for the two steps. Suppose now that the processes are carried out irreversibly with pressure dropping discontinuously from 100 atm to 10.0 atm in...

A piston containing 0.75 moles of a perfect gas at 25 degrees C
is moved isothermally from a starting volume of 8.305 L.
Calculate the work in joules if the piston is moved irreversibly
against a constant external pressure of 4.100 atm. We weren't
giving final volume so I am unsure of what to do. I tried to use
P1V1 = P2V2 because the final pressure is equal to external
pressure in an irreversible process. But then my final volume...
